We’ve heard the expression “you are what you eat.” When it’s crunch time, we tend to engage in all sorts of unhealthy habits that further increase our stress levels. That pizza? Bad idea. If your anxiety is spiraling out of control, food should be your ally, not your enemy. So if you find yourself cranky, tired and even clinically depressed, try these 11 mood-boosting foods.

1. MILK

Your brain needs an amino acid called tryptophan in order to make serotonin, a neurotransmitter nicknamed the brain’s Prozac, thanks to its happy-making and calming effect. Prozac works by conserving the brain’s serotonin, but tryptophan helps you make more of your own. Milk also contains antioxidants that help destroy free radicals associated with stress. Have some skim milk with your cereal for breakfast or pour yourself a tall, cold glass and use it as an excuse to scarf down a few chocolate chip cookies.

2. CHOCOLATE

Chocolate contains a host of chemicals to brighten your mood, including anadamine, a neurotransmitter that targets the same parts of the brain as THC, the active ingredient in cannabis. But chocolate contains such minuscule levels of anadamide, you’d need to eat kilos of it in order to make any impact on the amount that’s circulating in the brain naturally. So, why does chocolate give us the buzz it does? Scientists believe other chemicals in chocolate cause anadamide to hang around in the brain for longer, enhancing its stimulant effect. The sweet stuff also boosts our levels of endorphins, the brain’s natural happy hormones.

3. WHOLE-GRAIN RICE OR PASTA

It’s a good thing carbohydrates are finally back in style now that everyone has realized those low-carb diets were a bunch of hooey. Eating carbohydrates boosts serotonin levels (thus have a calming, soothing effect), and slow-release ‘complex’ carbs keep you sustained, helping you to stay mellow and preventing between-meals rattiness. While all carbs will give you this kick, stick to whole-grain bread, rice and pasta. Simple carbs like white bread and pastries will only give you a momentary boost followed by a crash, and they will make you pack on the kilos. On the other hand, whole grains (complex carbs) are digested more slowly and will thus keep you feeling fuller — and conceivably happier — for a longer period of time.

4. MACKEREL

A study in Finland found that people who eat more fish are 31 percent less likely to suffer from depression. Oily fish like mackerel are the best source of omega-3 essential fatty acids, which help prevent the blues. They boost serotonin levels and also enhance your brain’s receptiveness to the neurotransmitter. High-dose omega-3 supplements can even help patients suffering from clinical depression. Most types of fish are also replete with all-important B vitamins, particularly the renowned stress fighters B6 and B12. In fact, B12 is one of the most important vitamins involved in the synthesis of the “happy” brain chemical serotonin.

5. BROCCOLI

Yet another food that is chock-full of stress-relieving B vitamins, broccoli has the added benefit of containing folate (folic acid), which is also part of the B vitamin family. And since low levels of folate have been linked to depression in many studies, including research following thousands of people in Finland and California, it stands to reason that if you keep your folate levels up, you’re less likely to be down in the dumps.
